Next and probably the last things to change to make it look more kaleidoscopical::
1- Fuse four images in each quadrant. The same twice but flipped horizontally and vertically.
2- Image opacity. Do different trials with different opacities and see which is the best for the final result.
3- Do different trials with the angle of rotation and see what fits the best with a kaleidoscopic-like outcome.
4- Take into account the amplitude of sound in each place I test it and change the sensibility according to it.
